Somthing I found useful, when you are putting on your new rubber boot around the ball joint, make sure you pick up a piece of 2" round exhaust pipe, I found an adaptor for $1-$2 at the local hardware/autoparts store that did the trick. Place this pipe around the rubber boot and it will allow you to use a mallet to carefully put the boot on. This ensures that it goes on evenly and you won't rip the boot in the process.
